摘要
本文是在 NaoH-CO_2体系模拟铜熔池熔炼传质过程的基础上,对影响熔池传质过程的主要因素进行了试验研究,通过试验确定了各主要因素对传质过程影响的程度,根据大量数据的统计分析,求出了传质过程的数学模型及不同条件下的容量传质系数,并就风量对传质过程的影响进行了分析.
The influence of the principle parametres in the NaOH-CO_2 system water model on mass transfer in the bath of bicabinet coppermaking is studied.A mathematical model of the mass transfer is developed and the mass transfer coefficients are obtained under different experimental conditions.The effect of the flow rate of injected gas on the mass transfer is also discussed. It is found that in copper fused bath smelting processes among all the facts which affect the mass transportation,wind rate is the most important one,the distance between nozzles is more favourable to mass transportation than that of symmetry arrangement.The AK_L-Q and the bottom of the reactor is the second one,and the inflow angle of the nozzle is the third one. Staggered fixing of nozzles diagrammatic curves drawn under overall conditions has shown that AK_L increases with the increase of wind rate,from which an economical and reasonable wind rate could be found in practice.Based on the statistic analysis of the multi-facts orthogonal design,a mathematic model for the mass transportation has been established,with which mass transportation processes of various conditions could be analyzed guantitatively.
